摘要
针对基于可靠性理论的故障诊断模型 ,分析了该诊断方法中存在的不足 ,应用模糊数学的基本概念和方法 ,将精确型的故障判据拓广为模糊故障判据 ,给出了不同情况下故障概率的计算公式。在算例中 。
In this paper, the shortcoming of fault diagnosis model based on reliability theory was analyzed. The accurate judgment border was extended to fuzzy judgment border by using basic concept and method of fuzzy mathematics. The formulas of fault probability under different conditions were deduced. Finally, an example was given and the results of two methods were compared.
